Method for reinforcing bridge and culvert abutment rear transition section roadbed through miniature steel pipe piles
The invention relates to the technical field of highway construction, in particular to a method for reinforcing a bridge and culvert abutment rear transition section roadbed through miniature steel pipe piles. The method comprises the following steps that the range of a slope to be excavated is determined; holes are punched along the edge of the slope to be excavated, and grouting pipes are driven into the holes; grouting is performed through the grouting pipes; and slope excavation and foundation pit excavation are conducted after cement paste reaches the strength. According to the method for reinforcing the bridge and culvert abutment rear transition section roadbed through the miniature steel pipe piles, before excavation, the grouting pipes are driven in through drilling, then grouting is conducted through the grouting pipes, after grouting, the overall strength of the slope is high, and the stability of the slope is effectively enhanced; the supporting mode is high in construction speed, and the construction efficiency is improved.
本发明涉及公路施工的技术领域，具体而言，涉及微型钢管桩加固桥涵台后过度段路基方法，包括如下步骤：确定待开挖边坡范围；沿待开挖边坡的边沿打孔并打入压浆管。并通过压浆管压浆；水泥浆达到强度后进行边坡开挖及基坑开挖。本发明的微型钢管桩加固桥涵台后过度段路基方法在开挖之前先采用钻孔打入压浆管，然后在利用压浆管进行压浆。注浆后，边坡的整体强度高，有效增强边坡的稳定性。这种支护方式施工速度快，提高施工效率。
